used in connection with the keeper shown in Fie. 5.

n the embodiment illustrated, the device constituting this invention is shown applied to a window of usual construction having the ordinary frame F, upper sash S and lower sash S mounted to slide in the usual guideways of the frame.

The upper sash S has a socket 1 in the outer face of the upper end oit' each side rail SR in which is secured a thimble bur 2 having lan annular attaching flange 3 apertured to receive screws for securing it tosaid rail. An eye bolt l yisadjustably mounted in each bur 2, the eye 5 thereof being angular to ree ceive a correspondingly shaped end of a `rod 6 to prevent turning of said rod, said rod end being threaded to receive a nutdisposed above the eye bolt 4 whereby said -i'od is supported. This eye bolt 4 Eperforms the double function of a rod support and as means to prevent turning of the rod, also as means for attachment of a coiled spring 7 one end of which is engaged with said Vbolt l as shown in Fig. 2, and the other end is secured to an eye S on the header rail of the frame. "This spring 7 exerts its tension to balance and lift sash S and to return it to normal closed position after it has been lowered.

The rody 6 which may be of any suitable `or desired length is mounted to slide in a guide 9 carried by one side of the frame F and which is here shown in the forni of a 'keeepeig Ushaped in cross section and having attaching flanges 10 at one end, by means of which it is secured to the vframe F. See Fig. 2. This combined 4guide and lock is otherwise similar in construction to lock 16 shown in detail in Figs. 4 and 7 and soon to vbe described. Mounted to reciprocate in the cross bar of the keeper 9 is an eye bolt l1, the eye of which extends between the side walls of the keeper and through which is passed rod 6. The shank of this bolt 1l which yprojects outwardly through the cross bar of the keeper 9 Vis threaded to receive a thumb nut 12. This nut l2 hasa sleeve 13 .extending longitudinally from its inner face Aand in which is designed to be housed a coi-led spring 14;, one end of which bears against the inner end of said sleeve and the other 4against the outer face of Vthe cross bar of the keeper, and exerts its tension to hold the .eye of bolt l1 in yielding` engagement with the inner face of rod 6. This inner rod face is provided with a. plurality of longitudinally spaced notches 15, any desired number' of which may be employed and which are preferably rectangular in cross section having a flat or rectilinear wall 15', and with which are designed to be engaged the eye of bolt 11 so that said rod, when engaged by said eye, is held against longitudinal movement in the keeper and against rattling. It will be seen that by depressing nut 12 against the tension of spring 14C that the eye of said bolt will be moved away from the notch inyrod 6' with which it is engaged and thus permit said rod to be moved longitudinally and immediately that pressure is released on said nut, the eye of said bolt will again engage the first notch in the rod which passes over it and thereby automatically lock the rod and hold it until manually released. It willthus be obvious that this lock while automatic in its ordinary operation may be locked against movement and made to operate as a deadlock by screwing nut 12 tightly against the cross bar of the keeper so that no movement of the eye bolt can take place while the nut is in this position.

This rod 6 has an operating nger grip or handle, `here shown in the form of an eye 6 at its lower end, but obviously it may be in any other desired form.

Locks 16, similar in construction -to the lock just described are carried by the upper end of the lower sash S on opposite sides thereof, but being exactly alike in construction, one only will be described in detail. This lock comprises a keeper 17 substantially U-shaped in cross section, with registering openings as 18 in the side walls thereof and through which the rod 6 is designed to pass. This keeper is secured to the sash rail by means of apertured lugs 19 which project laterally from its free ends, seemore clearly in Fig. 5. An eye bolt 20 similar in construction to eye bolt 11 above described, which is carried by the window frame, has the shank thereof extending through an aperture 21 in the cross bar of the keeper 17 and the eye 21 on its inner end receives the rod 6 between the side walls of the keeper 17 and is designed to engage the notches 15 thereof in the same manner that .the eye of bolt 11 above described, engages them. The bolt 20 is provided with a nut 23, similar to the nut 12 above described, having a sleeve or skirt 24; which encircles a coil spring 25 and by means of which the eye of said bolt is held in yielding engagement with the rod and thereby designed to enter one of the notches 15 in said rod when the rod is moved longitudinally through keeper 17 so that the lower sash S may be moved up or down on said rod and locked in adjusted position by the engagement of its boltf20 with one of the notches in the rod and when it is desired-to fixedly secure the sash to the rod, this is accomplished by screwing the nut on the bolt 2O until the eye is firmly locked against all possible disengagement relative to the rod. The eye of the bolt 20 has its outer wall made rectilinear to engage the flat inner wall of one of the notches 15 so that all rattling is prevented owing to the tight drawing together of these flat faces by means of the spring 25.

From the above description it will be obvious that the lower sash S may be raised or lowered relatively to the upper sash S by releasing the bolt 20 from the rod 6 in the manner above described and sliding said sash S up or down, and that by releasing the spring pressed nut on the bolt of said sash, the eye of said bolt will automatically engage one of the notches in said rod and thus lock the sash in adjusted position. It will also be seen that the lower sash and the upper sash mav both be moved within the frame by disengaging bolt 11 from rod 6 and moving said rod either up or down according to the position in which it is desired to place the sash. The downward movement of said rod with the sash carried thereby will operate against the tension of spring 7 and said spring will tend when the bolt 11 is disengaged from rod 6 to return the sash to normal raised position as shown in Figs. 1 and 2.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily 100 apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment 105 thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim In a sash lock, the combination of a rod, means for mounting it on a window frame, means for connecting said rod with one sash and a spring pressed gripping member for connecting it with the other sash and adapt- 115 ed to be positioned to engage said rod to lock the two sashes in adjusted position relatively to each other, said member being in the form of an inverted U-shaped keeper' including legs with laterally extending aper- 120 tured attaching feet, an eye bolt extending through the cross bar of said keeper with its eye housed in the Ikeeper between the legs thereof, said legs having registering apertures therein alined with the eye of said 125 bolt and through which said rod is designed to extend, the eye of said bolt being larger than the rod to provide for the lateral movement of said eye relatively to said rod and having a rectilinear outer wall, a hollow nut 130 threaded on said bolt outside said keeper, of said bolt to hold the parts against ratand a coiled spring on said bolt bearing at tling. 10 one end on the keeper and at its other end In testimony whereof I aHiX my signature on said nut whereby the eye of said bolt is in presence of two Witnesses.
